Flashcards in Femur Deck (11):
1

What type of bone is the femur?

Long bone (in fact, it's the longest bone in the body)

2

What is the main function of the femur?

Transmits force from tibia to hip joint

3

Name three muscles that attach to the greater trochanter

Gluteus medius, gluteus minimus, gluteus piriformus

4

Name two muscles that attach to the lesser trochanter

Psoas major and iliacus

5

Which ligament attaches to the intertrochanteric line?

Iliofemoral ligament (strong ligament of hip)

6

What's the difference between the intertrochanteric line and intertrochanteric crest?

Intertrochanteric line is anterior, whereas the intertrochanteric crest is posterior (both span between greater and lesser trochanter)

7

Where is the quadrate tubercle found and what attaches to it?

. Found on superior half of intertrochanteric crest
. Vastus medialis (one of the quadratus femoris muscles) originates from here and from the medial lip of the linea aspera

8

What is an intracapsular/subcapsular hip fracture? Who are they most commonly experienced by and how? What damage can it cause?

. Fracture within capsule of hip joint, distal fragment shunts upwards and laterally (leg shortened and laterally rotated)
. Most common in elderly people falling
. Can damage medial femoral circumflex artery, which can lead to avascular necrosis of the femoral head

9

What is an extracapsular fracture? Who are they most commonly experienced by and how?

. Fracture outside capsule of hip joint
. More common in young and middle aged people
. Blood supply to femur is intact so no avascular necrosis occurs
. Leg is shortened and laterally rotated

10

Which muscle attaches to the gluteal tuberosity?

Gluteus maximus

11

Describe the 'branches' of the linea aspera.

(Posterior view)
. Pectineal line is superior and medial, leading on from the anterior intertrochanteric line, below femoral head)
. Gluteal tuberosity is superior and lateral, below greater trochanter
. Medial supracondylar line is inferior and medial
. Lateral supracondylar line is inferior and lateral
